The invention discloses a multi-stage buffer bumper. The multi-stage buffer bumper comprises a front crossbeam and a back crossbeam. The back crossbeam is arranged on the front crossbeam. A buffer support frame is arranged between the front crossbeam and the back crossbeam. Left and right sides of the buffer support frame are provided with buffer support plates. Multiple air bags are arranged among the buffer support plates and the front crossbeam. Shock absorbers are arranged between the buffer support frame and the front crossbeam and between the buffer support frame and the back crossbeam. Multiple buffer springs are arranged inside of the buffer support frame.By adoption of the above mode, the multi-stage buffer bumper is capable of absorbing energy in a multi-stage mode in order to greatly reduce collision-induced impact and prevent a vehicle body against damage. The multi-stage buffer bumper has a simple structure and is safe and reliable.
